The invention relates to a rotary extending-retracting mechanism of an exposed device of an aircraft and belongs to the technical field of aircraft manufacturing. The rotary extending-retracting mechanism comprises a device cabin doorway frame, a rocker arm, a doorway frame connecting structure, an adjustable connecting rod, a contact switch, a driving rocker arm, a device cabin structure wall board, a connecting bolt, a driving rotation shaft, a following-up base, a device base, the exposed device, a device rotation shaft and a limiting structure. The rotary extending-retracting mechanism can achieve a rotary extending-retracting function of the device on the aircraft, has the advantages of being stable in transmission, reliable in fixing, light in weight and the like, is a novel rotary extending-retracting mechanism for the extending device required to be shortened by the aircraft and effectively utilizes a limited installing space of the aircraft.
Description
technical field [0001] The invention relates to a rotary retractable mechanism for aircraft exposed equipment, which belongs to the technical field of aircraft manufacturing. Background technique [0002] Usually, in order to complete specific tasks, the aircraft needs to load some equipment that protrudes from the surface of the aircraft, such as optoelectronic platform equipment, large antennas, etc. Some of these equipment are only used for a short period of time in a certain period of time. If they are directly installed on the surface of the aircraft, they will Affect the aerodynamic and stealth performance of the aircraft. The retractable design of such equipment can effectively improve the aerodynamic and stealth performance of the aircraft. [0003] The conventional retractable mechanism is in the form of vertical retraction, which requires higher longitudinal space of the aircraft and affects the structural arrangement of the aircraft.
